Question

I have a Rails 3 app where I am trying to populate a javascript variable with every Nation in my database (less than 300 nations) as a JSON object. This is the relevant line in my nations.js.erb file:

_this.nations = <%= Nation.all.to_json :only => [:id], :methods => :text %>;

When I call my js file in a browser, /assets/users.js which does a require of the nations file, the _this.nations variable is populated perfectly. When I try to do a precompile I get the following:

$> rake assets:precompile
$> rake aborted!
uninitialized constant Nation (in nations.js.erb)

So my question is this: is it possible to reference the Nation model, or any model, from within the js.erb file for precompiling? I also tried using my NationsHelper but my error just changed to uninitialized constant NationsHelper.

I’m fairly new to RoR so if relevant information is needed that I haven’t provided, please just ask.

If you have config.assets.initialize_on_precompile set to false somewhere then try enabling it

config.assets.initialize_on_precompile = true
